| 文章以黄河口湿地为研究区，在生态系统服务价值概念的基础上，提出了一种考虑成本投入的生态系统服务净价值估算方法，通过时间序列遥感监测，估算并分析了2019—2022年的黄河口湿地生态系统服务净价值。结果表明：（1）在黄河口湿地的11种生态系统服务类型中，生物多样性、固碳、食物供给和消浪护岸是主导生态系统服务，浅海水域、芦苇、盐地碱蓬和潮滩净价值能力较强。2022年生态系统服务净价值比2021年减少了4.08亿元，主要是2022年净价值能力较强的盐地碱蓬大面积消失导致。（2）尽管在2019年和2020年，典型生态修复项目在施工后的第一年净效益呈现负值，但应发挥的生态系统服务净价值已达到预期。（3）通过敏感性分析证明了消浪护岸、食物供给、固碳和生物多样性在众多生态系统服务中具有重要作用。生态系统服务净价值估算可以比较分析不同的湿地类型产生的最大净价值，为合理的规划和管理滨海湿地生态系统提供科学依据。 |

| Abstract: |
| Based on the concept of ecosystem service value, this study proposes a method for estimating the net value of ecosystem services considering cost inputs, and estimates and analyzes the net value of ecosystem services in the Yellow River Estuary wetland from 2019 to 2022 through time series remote sensing monitoring. The results indicate that:(1) Among the 11 types of ecosystem services in the Yellow River Estuary coastal wetland, biodiversity, carbon sequestration, food supply, and wave attenuation and protection are the dominant ecosystem services. The nearshore waters, reed beds, salt-alkali plants, and tidal flats show strong net value capacity. The net value of ecosystem services in 2022 decreased by 4.08×108 yuan compared with that in 2021, mainly due to the disappearance of a large area of salt-alkali plants with strong net value in 2022. (2) Despite the negative net benefits observed in the first year after the construction of typical ecological restoration projects in both 2019 and 2020, the net value of ecosystem services has reached the expected level. (3) Sensitivity analysis demonstrates the significant role of wave attenuation and protection, food supply, carbon sequestration, and biodiversity among the various ecosystem services. The estimation of net value of ecosystem services enables the comparison and analysis of the maximum net value generated by different types of wetlands, providing a scientific basis for the rational planning and management of coastal wetland ecosystems. |
